3dB TWEETER TOGGLE

If your listening room is very reflective, with smooth sheetrock walls, hardwood floors, and non-cushioned furniture, the sound can be overly “bright” and unnatural. Engaging the LCi tweeter attenuation feature (by selecting the “cut” setting) compensates for the effect of reflectivity in a hard room. Tweeter attenuation flattens room response, without hindering higher frequency response, for warmer, more realistic sound and more accurate imaging.

WALL DISTANCE TOGGLE

In-wall loudspeakers excel when placed more than 2' (60cm) from side walls. If position limitations demand that your loudspeakers be installed closer than 2' (60cm) from side walls, the close proximity of the surface can result in a response “bump” between 50 and 200Hz. This can cause in-wall speakers to sound “boomy.” The distance toggle switch flattens response and tunes out “boominess” without sacrificing deep bass response, for more lifelike sound. If the speaker is closer than 2' to a wall, engage the wall distance toggle (“Wall Dist.”) to match the <2' setting. Recommended speaker distance from side walls is 2' (60cm)

Adjusting the Tweeter (LCi-RTS105 ONLY)

Aiming the tweeter toward your listening position improves imaging and detail. If you are using LCi Series In-wall Loudspeakers as front/main home theater speakers, aim the tweeter toward your listening position. For rear/surround speakers installed in walls or ceilings, aim the tweeter toward

the nearest reflecting surface (an adjacent wall or ceiling) if you desire a more diffuse sound field. For more direct sound, aim the tweeters at your listening position.

Important Note: LCi-RTS Series Loudspeakers are not magnetically shielded and should not be placed closer than 1' (30cm) from a direct-view television or video monitor.

Stud-Lock Mounting Installation

The Stud-Lock Mounting System™ creates a rigid platform for the LCi-RTS105 and LCi-RTS100, increasing bass performance, clarity and reducing unwanted structure borne vibration. The installation inst-ructions supplied with each Stud-Lock Mounting System™ should be used in conjunction with your LCi Series owner’s manual. Please read your manual carefully to aid you in the proper installation

and hookup of your LCi Series in-wall loudspeakers.

Important Notes:

If you are using a Pre-Construction Bracket, always install the Pre-Construction Bracket before installing the Stud-Lock Mounting System™. Be sure to clear the Pre-Construction Bracket wire guide when installing the Stud-Lock Mounting System™.

If you have questions, please contact your Authorized Polk Audio Dealer or Customer Service at 1-800-377-7655 Monday through Friday 9am-6pm EST.
